,lie il known that` l. ll'mNRCr-l ifioxin'r, engineer, a subject oli the lhnperor of (lerlnan'y, residingI ai lexandroiewsli Per. No 5. ll'oseow. Empire oi Russia, have in rented 'new and useful Iuiproveinents in (bre-Supporhg oil which the following .is :ispecification.

lheiuveuiiou relates lo that kind of core supports iu which `the bearing;l plaies with 'ihe eooueeting stays consistof one piece of shee iron willi lol'lggiiudinal rib9 while each connecting; stay l'ixrnied ol" the rib of the blaul; detached 'from the, plate und bent back, iu these core supports the bending .Fmi-lq oi' the rib forming?Y the bridge een only,V be ell'eeied in 'he saule. direeiiiul, so Thai in the Finished suppmfl. the ribsl run ihe one opposite the other ou the suppori'iugi plaies. (lousequeuily lhe holes resultingA in the sul porlinrl plaies from lne` dctaehing` oi? the rib to leru! the, livridgge are opposite. hence are only present on one side of the b idee. so that ell'ective escape oi" Jche air is impossible on the other ride ole the bridge and therel'ore there is a possibilityY of the F'irumliion of bubbles. ln addition i'he oeeessiiy of :il-- ways bending; hach' iu the saine. direction the `rib lforuxiug` the bridge does not permit ol uiahingy core .supports with more, than two lufii'lges. Thot is a serious disadan laire. because praeiire requires core support` ol any desired length and willi the larger lengths a eorrespmidiugly increased number oi' bridges can be oblaiued, Ilot-h disadvantages of the said kind oli core supporis are overcmne by J[he inrentioi'i by the acl; lhat the bridges7 formed ouli oi [he rib by detachingfrom the sheet iron and by bending' back. are l'wis'ced about their longitudinal axes. ln this way is; obl'ained, wii'h core supports with one bridge as well as with several bridges. :diei-nale holes of che supY porting plaie., so that :are is iaken for proper escape oli the air ai each side oi. the bridge und l'he liormatioi'i oil.E bubbles is avoided thereby. To 'this added the greater resistance oli the twisted bridge against compression and ils easier WeldingY in. At the saine *time the desired increase in the number of bridges and hence the deIv sii-ed prolongaion oi the core support as well as the making of corner supports with any desired number of bridges is accomplished.

A. core support `vided with openings adj .series'ot' bearing-plates arranged end for end, and stays connecting oppositely dis- .lmg provided with an opening@y from which i ing plates or bearing plate parts f and g is situated opposite to theaperture z or' the other plate or plate portion of the same pair of bearing plates. Each stay a is therefore provided on each side withan aperture L in Vone of the bearing plates or bearing plate portions so that the air can escape on'l each sideof the stay.

Having new particularly described and i ascertained the nature oi" my said invention an in what manner thesaine is to' be peri formed, I deflare that what I claim is-- 1. A core support comprising spaced bearing plates having longitudinal ribs on their inner faces and connecting stays conneetinpr the plates, eaoh stay being a bent up portion g cnt from the'plate, bent .l at'right angles and twisted.

- Q. A core support comprising spaced bearing" plates having longitudinal ribs on their rner faces and connecting stays connecting s he plates,'eaeh stili' being a bent up portion f said rib and plate cut from the plate, bent l and twisted wherel'i) open ings in the plates are left on opposite sides of tlie stays.y

comprising' spaced bearing plates and emineetinpr stays connecting' the bearing plates, said plates .being proacent to the stmvs and on opposite sides ot' the stays.

one piet-'e core support eomprising two .series ot' bearing plates arranged end' tor end, the series being spaced'from eaelr' other, eaeh plate haring a rib onits inner laee; and connecting stays connecting the plaies and eut from the plates and ribsI and 7. A core support comprisingl spaced bean; in; plates having longitudinal ribs on their iriner faees and eonnecting stays connect-ing the plates, eaeh stay being a portion of said rib and plate eut fromthe plate. bent up and twisted.

8. A core support eoniprising spaced bearing plates haring longitudinal ribs on their inner faces and connecting` stays connectingI being a bent up' portion ot' said rib and plate eut from tbe plate, lient at right angles and twisted through 180 degrees only.

9. A one piece core support comprising two series of more than two bearing plates arranged end for end7 the series being spaced from each other, each plate having a rib on its inner face; and more than two connecting stays connecting the plates andl eut from the plates and ribs and twisted.
